WINDSHIELD WIPER.

Application filed October 22, 1926. Serial No. 148,447.

My present invention has reference to a sion between the nuts 8 and the bearings 6 windshield wiper for automobiles, and my object is the provision of a means for regu lating the contact of the rubber wiper or squeegee with the windshield, so that a pressure of the squeegee against the glass will be at all times properly regulated to assure the cleaning of the glass without injury to the rubber squeegee.

To the attainment of the foregoing, the invention consists in the. improvement as hereinafter described and definitely claimed.

In the drawings:

Figure 1 is a fragmentary elevation of an automobile illustrating the application of my improvement thereon.

Figure 2 is a side elevation of the improvement.

Figure 3 is a sectional view on the line 33 of Figure 2.

The rubber wiper or squeegee 1 is'supportthere are helical springs 10. The springs 10 40 serve to urge the rollers outwardly through the frame 2 when the nuts 8 and 9 are unscrewed.

The shafts 5 are adjusted to bring the rubber rollers 7 in proper contact with the windshield so as to regulate the pressure of the squeegee 1 against said windshield and by such simple arrangement the pressure of the squeegee against the glass plate is properly regulated to insure the plate being eflectively wiped to remove all moisture therefrom without injury to the windshield wiper. Too much pressure upon the squeegee or the windshield wiper causes the binding thereof against the glass plate when in operation and when not in operation the rubber will twist when the same is allowed to dry, while, of course, not enough pressure will cause the rain to blur on the windshield so it is thought ed in the usual manner, in a metal frame or the simplicity of my invention and the ad- 50 bod 2. The frame 2 is pivotally supported, as at 3, on the swingable operating rod 4:. The rod may be connected to the power plant of the automobile or the windshield wiper may be manually operated.

The rubber squeegee 1 does not extend the entire length of the frame or body 2. The ends of the said frame or body may be solid vantages thereof will be understood and. ap- ,pree1ated by those skilled in the art to which such invention relates.

Having described the invention, I claim A squeegee-carrying frame swingably sup- 5 ported. for wiping engagement with a trans parent plate. said frame. at the ends thereof having threaded shafts passing thereand passing through these ends there are through, and a bearing on each shaft for a threaded shafts These shafts have on rubber roller. nuts screwed in the threaded their outer ends bearings 6 for the shafts of shaft and contacting with the opposite edges rubber rollers 7. The threaded shaft is engagged by inner and outer nuts 8 and 9,

of the frame. and a spring on each shaft exerting a tension between the bearing and which contact respectively with the inner the nut adjacent to said bearing.

and outer faces of the body or frame 2. Also surrounding each shaft 5 and exerting a ten- In testimony whereof I aflix my signature.
